Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 Shown, the method that the embodiment of the present invention provides by controlling the trichlorfon concentration to improve Chinese Limulus larva survival rate comprises the following steps:

[0040] S101: After the preliminary test, set 6 trichlorfon concentration gradients of 0g / L (control), 0.5g / L, 1.0g / L, 2.0g / L, 4.0g / L, and 8.0g / L, from 25 Prepared by dissolving seawater. Set 3 parallels for each concentration gradient, each with 10 horseshoe crab se...

Abstract

The invention belongs to the technical field of tachypleustridentatus larva culture, and discloses a method for increasing the survival rate of tachypleustridentatus larvae by controlling the concentration of trichlorfon. The safety concentration of trichlorfon is 0.3813 g / L; the survival rate of tachypleustridentatus larvae is 100% by using trichlorfon with the concentration of 2.0 g / L or below; the LC50 of trichlorfon on tachypleustridentatus is 0, 7.88 g / L, 5.912 g / L, 5.912 g / L, 5.912 g / L, 4.143 g / L, 4.038 g / L and 3.813 g / L. at 12 h, 24 h, 36 h, 48 h, 60 h, 72 h, 84 h and 96 h respectively. According to the method, the safe concentration and intensity of trichlorfon for influencing the survival of tachypleustridentatus larvae in the first stage are obtained, and the survival rate of tachypleustridentatus larvae is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for improving the survival rate of Chinese horseshoe crab larvae by controlling the concentration of trichlorfon. Background technique [0002] Chinese horseshoe crab (Tachypleustridentatus), also known as three-thorn horseshoe crab, belongs to Arthropoda (Arthropoda), Chelicerata (Chelicerata), limb mouth (Merostomata), Xi-phosura (Xi-phosura), Limulidae (Limulidae), Eastern Limulus (Tachypleus) is a warm-water benthic animal on the coast of the western Pacific Ocean. It first appeared in the Paleozoic Ordovician period nearly 400 million years ago. It is mainly distributed in the Seto Inland Sea and Kyushu Island in Japan, the southeastern coast of China, and Taiwan, China. The west coast of the island, Vietnam, the Philippines, the Indian Ocean side of Sumatra, the east of Java, North Borneo in Malaysia, and the east and north coasts of Kalimantan. Ex...
